Balsamic & Bourbon Barbecue Sauce - cooking recipe

Ingredients

1 large onion
4 garlic cloves
2 cups tomato sauce
1/2 cup Bourbon
1/4 cup brown sugar
1/4 cup balsamic vinegar
2 tablespoons spicy brown mustard
2 tablespoons tomato paste
2 tablespoons soy sauce
1 tablespoon hot chili paste (or equiv. amount of red pepper flakes)
1 tablespoon liquid smoke

Preparation

Dice onion very finely, saute' with pressed garlic until soft.
Add bourbon and chili paste (or pepper flakes), reduce over low flame.
Add remaining ingredients and simmer until reaching the desired consistency (about 45 minutes). Tastes better over time, so prepare a few days in advance if you can.
If not salty enough for your taste, add soy sauce rather than salt.
